         3 . A display device having a function of displaying a broadcast program in accordance with preference of a user, the device comprising:
 a priority information storage unit for storing a priority for each category into which the program is classified;   a priority calculation unit for, when a broadcast program is viewed, calculating a priority for the category in order to increase the priority of the category to which the viewed broadcast program belongs and decrease each priority of any other category than the category to which the viewed program belongs;   a program information collection unit for acquiring program information of the broadcast program at a predetermined opportunity;   a display program control unit for specifying the category, the priority of which is the highest, and selecting one or more programs belonging to the specified category among programs currently broadcasted; and   a program display processing unit for displaying the selected one or more programs.   
     
     
         4 . The display device according to  claim 3 , further comprising a program feature information storage unit for storing correspondence information indicating a correspondence relation between the category and a feature word representing feature of the program that is classified into the category, and
 a program feature extraction unit for extracting a feature word representing feature of the program from the acquired program information for each program,   wherein the category includes a first category into which the programs are classified according to a superordinate concept and a second category into which the first category is further finely classified, and   the program feature extraction unit specifies the second category to which the program belongs by using the feature word extracted from the program information and the correspondence information for each program, and   the priority calculation unit calculates the priority of the specified second category.   
     
     
         5 . The display device according to  claim 3 , wherein the priority calculation unit decides the value of the priority so that the calculated priority of each category or subcategory falls in a range between of a predetermined upper limit and a predetermined lower limit. 
     
     
         6 . The display device according to  claim 3 , further comprising a setting unit for making the setting for increasing or decreasing the priority performed by the priority calculation unit in accordance with a selection indicated by the user. 
     
     
         7 . A remote operation device which sends an instruction signal to a display device having an instruction signal receiving unit for receiving the instruction signal and a program display processing unit for displaying a broadcast program instructed by the instruction signal, the remote operation device comprising:
 a priority information storage unit for storing a priority for each category into which the program is classified;   a priority calculation unit for, when a broadcast program is viewed, calculating a priority of the category in order to increase the priority of the category to which the viewed program belongs;   a program feature information storage unit for storing correspondence information indicating a correspondence relation between the category and a feature word representing feature of the program that is classified into the category;   a program information collection unit for acquiring program information of the program at a predetermined opportunity;   a program feature extraction unit for extracting a feature word representing feature of the program from the acquired program information for each program;   a display program control unit for specifying the category, the priority of which is the highest, and selecting one or more programs belonging to the selected category among programs currently broadcasted; and   an instruction signal sending unit for displaying the program name of the selected program and sending to the display device an instruction signal whereby the program selected by the user is indicated as the viewing object;   wherein, when the program feature extraction unit extracts the feature word associated with a certain category from the program belonging to another different category from the associated category, the priority calculation unit temporarily changes the priority of the category to which the program, from which the feature word is extracted, belongs by using the priority of the category with which the feature word is associated.   
     
     
         8 . A remote operation device which sends an instruction signal to a display device having an instruction signal receiving unit for receiving the instruction signal and a program display processing unit for displaying a broadcast program instructed by the instruction signal, the remote operation device comprising:
 a priority information storage unit for storing a priority for each category into which the program is classified;   a priority calculation unit for, when a program is viewed, calculating the priority for the category in order to increase the priority of the category to which the viewed program belongs and decrease the priority of any other category than the category to which the viewed program belongs;   a program information collection unit for acquiring program information of the program at a predetermined opportunity;   a display program control unit for specifying the category, the priority of which is the highest, and selecting one or more programs belonging to the category among programs currently broadcasted; and   an instruction signal sending unit for displaying the program name of the selected program and sending to the display device an instruction signal whereby the program selected by the user is indicated as the viewing object.   
     
     
         9 . A computer-readable medium storing a display program that is executed on a computer having a function for displaying a broadcast program in accordance with preference of a user, the display program causing the computer to function as a display device comprising:
